How common is Kohler disease?

Kohler disease is considered a rare condition. To our knowledge, there are currently no accurate estimates of its prevalence. The condition is much more common in boys than girls. However, girls with this condition are often younger than affected boys; this is presumably due to the earlier onset of ossification (the hardening of bones) in girls.[1]
